Generally, any device that has the ability to sense the surrounding environment can be considered as a sensor node. A Wireless Sensor Network (WSN) is a group of sensor nodes that cooperate with each other, it may contain a few numbers of sensors or it can consist of thousands of sensors. Wireless sensor networks can be used in wide range of applications such as measuring temperature, humidity, pressure, noise level, monitoring the vehicular movement, military applications and health applications. One of the main crucial issues can face the operation and the surveillance of wireless sensor networks is energy consumption.
